Influence of finishing temperature on the mechanical properties of conventional hot rolled steel bar

  The conventional mill operators are faced with challenges of producing reinforcing steel bars of adequate strength characteristics. This stems from the inability to effectively control and monitor process variables such as temperature, strain-rate and cooling. These parameters collectively determine the microstructure and invariably the mechanical properties of the rolled bars. However, the finishing...

An investigation of the effect of hall current and rotational parameter on dissipative fluid flow past a vertical semi-infinite plate

  Magneto hydrodynamics (MHD) stokes problem for a vertical semi-infinite plate in a dissipative rotating fluid with hall current has been considered. The partial differential equations governing the problem are framed and then solved using numerical methods of implicit finite difference approximations.  An analysis of effects of parameter on the velocity (both primary and secondary) profiles and...
